Application filed November 9, 1912. Serial No. 730,328.

To all whom it may concern Be it known that I, JOSEPH W. WEIss, a citizen of the United States, and a resident of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Collapsible Cartons, of which the following is a specification.

This invention relates to collapsible car-. tons, more particularly to the type of carton which is adapted for use as a suit box or other form of box having the general proportions of a suit box.

In the character of box above designated, many forms have been hitherto devised for rendering the same collapsible. In all of these forms, however, a comparatively flexible material has been employed which is easily bent, so as to be set up by a tab and slit connection or some other special form of connection. Collapsible boxes built up of this comparatively flexible material are not rigid when set up and often require considerable time and skilful manipulation to properly set them up.

In the present invention, I have devised a collapsible carton which may be formed of a stiff material such as corrugated board, is inexpensive to manufacture, easily and simply set up, and when so set up is strong and rigid and maintains its shape properly.

In carrying ullt the invention, I provide a blank of some stifi' material as corrugated board and score the same adjacent to its longitudinal and lateral edges by any suitable method as by passing the blank through scoring rollers in a scoring machine. Ad acent to each lateral edge three scores are formed, the middle of the three being wider than the others, while the end score is preferably formed on the side of the board opposite to the other scores. The material is then sawed in or otherwise cut, preferably on a diagonal line through or adjacent to the longitudinal scores, leaving two end flaps, two side flaps and a pair of tongues extending from the side flaps.

In assembling the box, the side flaps are turned up, the tongues extending therefrom are turned in and the end flaps are turned over these tongues and are wedged in through the contact of their diagonal edges with, the longitudinal sides, and are thus held firmly in position. This wedgingis assisted by reason of the fact thatthe edges of the end flaps are somewhat flexible through the scoring and thus afford a substantially yieldable, resilient portion which firmly holds the flap in place. When set up, these longitudinal and end flaps constitute the sides of one part of the box. In the accompanying drawings illustratmg one embodiment oi the invention, Figure 1 is a plan view of one part of the carton, collapsed. Fig. 2 is a section taken along lines 2-2 of Fig. 1. Fig. 3 is a perspective view illustrating the two parts of the carton open, located one over the other. Fig. 4 is a fragmental detail view showing the inclined edge of the end portion of the box on an exaggerated scale.

The carton consists of two parts which are telescoped one into the other and are of substantially similar construction. One of these parts only will be described, the detail features of which will apply to both'parts.

Referring particularly to Fig. 1, the main body of the carton consists of a bottom 1, side portions 2 and end portions 3, all "formed from one integral blank of stiff and light material such as corrugated board. In order to form the side and end portions out of the blank, the latter is run through a scoring machine such as a machine having scoring rolls throughwhich the blank is fed. The latter is thus scored .or indented so as to provide weakened or flexible grooved portions along which the material will easily bend or fold. The blank may be run through once for forming the longitudinal scores or grooves 4 and a second time to form the transverse scores 5, 6 and 7.

y The ends 3 are located between the scores 5 and 6 and the fiap 8 together with its ex tension 9 extend outward from each end.

: Thegroove 6 is wider-than the grooves 4,

5 and 7 for the purpose hereinafter described while the groove 7 is preferably formed on the side of the blank opposite from the side on which the other grooves are located. After the blank has been so scored, it is cut in any suitable manner, as by being sawed in by some suitable saw, at or adjacent to the ends of the scores or grooves 4. These cuts terminate at the score 5, and thus the ends 3 together with the flaps 8 and 9 are separated from the sides, the latter being formed with outwardly extending tongues 10. The tongues 10 are preferably cut away so as to terminate in a line with the score 7, thus leaving the tongues with only one score across their up and the flap 8 is turned over these When the box or carton 1S tobe assembled, the sides 2 are bent up, the tongues 10 p are turned in, and then the ends 3 are bent tongues, the laterally inclined edges 11 wedging in against the sides 2 and thus holding the flap from displacement in the position indicated in Fig. 3. The extension 9 is turned in and disposed so as to rest against the bottom 1, and its lateral edges also wedging in against the sides 2. The flap 8 folds easily over the tongues 5 by reason of the wide score 6 which forms a wide, flexible portion easil permitting a sharp turn of the sti material. The edges 11- may wedge in very tightly against the sides 2, particularly so by reason of the flexibility-and resiliency of the material adjacent these edges produced by the score along which the out had been made. These flexible or resilient portions although extending normally beyond the width between the sides of the box,-still may be readily forced into position to firmly gnp the sides of the box.

- It will be seen that I have provided a collapsible carton formed of stifl material which may be readily set up and held in position by the frictional contact of the material itself without the aid of any special device such as metallic clips, tabs and slits, etc. I have also devised a form of constructi'on which makes it possible to obtain a very firm frictional hold with a stifl material.

Having thus described my invention, I claim as new It. A collapsible carton comprising a bottom, side portions and end portions, there being scores in the material between said bottom and said side portions, said end pornriaaoa tions having edges extending obliquely across said scores, said edges being adapted to wedge in against their side portions, the

Widest portion of said end portions being wedged iri between the side portions adjacent said bottom.

2. A collapsible carton comprising a bottom portion and side and end portions, said end portions having oblique edges which wedge against said side portions when the carton is set up, the widest portion of said end portions being wedged in between the side portions adjacent said bottom.

3. A collapsible carton comprising a bottom portion and side and end portions, there being scores between said bottom and side and end portions, each of said end portions having a flap adapted to turn over and lie against said end portion, said flap having outwardly flaring edges to wedge in against said side portions, there being a heavy score between said end portion and flap, and the Widest portion of said flaps being wedged in between the sides adjacent said bottom.

4:. A collapsible carton, comprising a bottom portion and side and end portions, there being scores between said bottom and side and end portions, said end portion having a flap adapted to turn over and lie against said end portion, said flap having outwardly flaring edges to wedge in against said side portions, there being a heavy score between said end portion and flap, said flap having a continuation therefrom adapted to rest against the bottom'portion, and there being a score between said flap and continuation located on the side opposite from the other scores.
